WASTE VALVE FOR BATHTUBS AND LAVATO'RIES.

Original No. 1,630,352, dated May 371, 1927, Serial No. 142,278, led vOctober 1S, 1926. Application for reissue filed December 27,

This invention relates generallyto a waste valve for bathtubsand lavatories.

The object of the present invention is to provide a waste valve which will take the place of the ordinary chain and stopperin common use and whichwill completely eliminate the chain, which after a period of use becomes more or less unsanitary.

Another object of the invention is to provide a waste valve which can be quickly and easily opened or closed and which can be retained in open position when desired andr another object is to provide a valve which is non-removable and consequently isnot likely to be misplaced or stolen. Another and very important object of the invention is to provide 'for the quick and easy connection of the device to the bathtub without the employment of especially designed tools or technique.

IVith these various objects in view the invention consists in the details of construction and in the manner of combining or arranging the same, all of which will be fully described hereinafter and set forth in the appended claims. v

In the drawings forming a part of this specification,

Figure 1 is a side elevation of my im-V proved device ready for insertion into a bathtub or a lavatory,

Fig. 2 is a vertical sectional view showing the valve raised or opened,

Fig. 3 is a top plan viewof the device, and" Fig. 4 is a sectional plan on the line 4-4 of Fig. 2 and looking downwardly.

In carrying out my invention I employ a metallic ring 10 externally threaded atA 11 and provided with an outwardly extending annular flange 12 at the upper end thereof and a tapering or beveled valve seat l13. This threaded and flanged ring or sleeve is screwed through the bathtub opening from above into the drain elbow thereof and the flange 12 seats within a recess usually provided for the same, so that the top of the sleeve is flush with the bottom of the bathtub.

The sleeve 10 is formed with a spider hav-A ing radial members 111 and a. centrally'bored hub 15, and working up and down in this hub is the stem 16 of tapered valve part 1 7 said valve being sized and shaped to fit snuglyupon the beveled seat 13. This valve 1927. Serial N0. 242,825.

is also provided with any suitable knob 18 or other device, by means of whieh'it may be manipulated as herein described. Y

vIn the drawings the stem'16 is .shown threaded into the tapped v alve part 17, but it will be understood, of course, that it may be made integral therewith, if so desired. The hub 15 is slotted vertically, as indicated at 19, and the stem 16 is `provided with a` laterally projecting pin 20 which travels up and down in the slot 19, when the valve is being raised and lowered. In order to maintain the valve in its open position, it

may be given a turn in either direction, after l the pin20 has been lifted clear of the hub, which is provided with a stop 21against which said pin 2() is adapted rto Contactv and limit the. turning movement of the valve part. This lug or stop 21 is so positioned that the valve may be turned in either direction to eifect the support ofthe valve in its elevated position. I-Iowever, this improvement is not necessarily limitedto the precise supporting means herein shown and above described. y y

The stein 16 is provided' with a terminal collar 22 to prevent said stem being withdrawn from the hub. This collar may be an integral part of the stem 16 or it may be attached thereto, and it may be either a complete collar or merely a lateral projection, so long as the same is of such size as to prevent withdrawal.

The stem 16 is of such length and the pin 20 is so positioned thereon that when the valve is completely opened, there is ample space between the valve and ring to insert a screw driver 23 or any other suitable tool for the purpose of turning the ring to screw the same into the bathtub or lavatory without yinjuring in any manner `the valve or seat. This eliminates the formation of the ring in any peculiar mannervand also eliminates the use of special tools or techniquefor the placement and securing of the vdevice in the bathtub or lavatory. The valve stemfwhile being of such length as to elevate the valve suiiiciently for the introduction of the screw driver or other tool is not suiciently long to Contact with the bottom of the drain el bow nor will it interfere with the free exit of the water. y f

In order to close the valve it is only necessary to turn the stem until the pin 20 is in register with the groove 19 and then permit the valve to drop upon its Seat. To open the valve it is only necessary to lift the same vertically and giveV the stem a turn in either direction until the pin 20 contacts with the stop lug or projection 21.

It will thus be seen that I provide an eX- ceedingly cheap, simple and efcient form of waste valve which will effectively carry out all of the objects hereinbeforefrecited. More particularly, this construction .readily lends itself to the ready insertion and removal of the Avalve structure interior-ly of vthe bathtub from above its drain elbow.

Having thus described my invention, what I claim is: y. y

1. As a .new article .of manufacture, a

waste valve for bathtubs comprising. an eir-l ternally threadedsleeve provided at itsupper end with an outwardly extending flange, said sleeve having a valve seat at its upper end, va centrally disposed spider having a longitudinally slotted hub, said hub.`

having an upwardly projecting stop lug, and a valve provided with a stem, said stem having a laterally projecting pin intermediate its ends and a laterally projecting stop at its lower end, the length ofsaid stem being such as to hold the valve elevated a su'lcient distance above the spider to permit a tool to be brought into engagement with said spider for the Apurpose of screwing the sleeve into the bathtub opening.

2. Asia new article of manufacture, a waste valve for bathtubs comprising an externally'threaded sleeve provided at itsy upperend with an outwardly extending flange, said sleeve` having a beveled valve seat at itsl upper end, atapered valve part adapted normally to seat therein and provided with a depending central supporting stem, an elongated hub adapted to accommodate vsaid stem land permit its vertical movement therein; and provided with a radial connecy tion interiorly of the threaded sleeve, the

length of said stem being such as to permitv the elevation of the valve 'part a sufficient 4distance to allow a tool to be brought into engagement withsaid radial connection andA stem for the purpose of screwing the sleeve into the bathtub opening, and means for temporarily maintaining said valve part in its elevated position.

In testimony whereof, I hereunto affix my signature.

JOHN N. MORTIMER.
